boards often have RAID controllers. RAID technology takes advantage of Serial Advanced Technology Attachment (SATA) and the integration of RAID into the Intel Q965/ICH8-D0 chipset.

two hard drives At a higher reliability cost with faster performance, HP Compaq dc7700 Business PC Convertible Minitower and dx7300 Microtower also allow for RAID 0 with three hard drives. RAID 0 with two or three hard drives is a supported configuration. RAID 0 with three hard drives is shown in - HP Dc7700 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and - Page 7
way to increase system storage reliability and a great value proposition, RAID 1 is the only RAID configuration that HP preconfigures for HP Compaq dc7700 and dx7300 Business PCs. RAID 1 provides high availability with minimal performance impact, as well as greater reliability compared to a single - HP Dc7700 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and - Page 8
5 with three hard drives RAID 5 has been used in servers for many years and is one of the most common types of RAID. RAID 5 uses striping with parity data in distributed blocks across all member disks. Therefore, the mass storage controller can simultaneously write new information to two hard drives - HP Dc7700 | Redundant Array of Independent Disks (RAID) on HP Compaq dc7700 and - Page 9
